Why couldn't Einstein accept that the universe was expanding?
Its not that he couldn't, he eventually did and declared his "cosmological constant" the biggest mistake in his life.The situation was when Einstein developed General Relativity the prevailing cosmological theory was the Steady State Theory, that the universe was static. However General Relativity predicted that the universe could NOT be static: it must be either expanding or contracting. To correct for this apparent "error" and conform to the prevailing theory, Einstein added an arbitrary fudge factor that he called the "cosmological constant" that could be tweaked as needed to keep the General Relativity predictions in accordance with the Steady State Theory.When it was clearly shown that Hubble's data was right and the universe was expanding, he willingly deleted the "cosmological constant" from Relativity.
Is mass constant in all three states of matter?
By definition, the mass of a certain amount of substance is a constant regardless of the state it is in. But you should realize that there are actually four, not three, states of matter. Matter in the ionized state is called plasma, which comprises 99.99% of all visible matter in the universe.
What is the motto of Incredible Universe?
The motto of Incredible Universe is 'If it's not in the Universe, it doesn't exist!'.
In the infinite universe theory does the universe have no beginning and no end just like numbers from negative numbers going to positive numbers?
There is reason to believe that there is an infinity of space out there, just as time is infinite, both in the past, and in the future. At some stage in this infinity of time and space, our universe began. In fact, the multiverse hypothesis says that our universe is only one of many such universes that have come into existence, or will in the infinite future. However, Einstein proposed that our universe (and therefore each universe if the multiverse hypothesis is correct) is curved, so that it in some way has an outer boundary contrary to Professor Hawkins saying the universe may have no boundary as the universe is possibly self contained. Minority viewpoint: The Infinite Universe Theory states that the universe exists everywhere and for all time. Thus the universe had no beginning, although each part of it has a beginning and an ending, being assembled from other parts in the necessarily Infinite Universe. This is in tune with the First Law of Thermodynamics (Conservation), which states that "Matter and the motion of matter neither can be created nor destroyed." The opposing assumption is Creation, the belief that something could be created out of nothing. The Big Bang Theory of the origin of the universe is wildly popular largely because most people follow religious tradition in assuming Creation. In tune with that logic, modern physicists accept numerous odd claims such as the shibboleth that space could be curved even though it is supposed to be completely empty.

When was the formation of the universe?
The Universe has an age estimated to be about 13.8 billion years.
What is the current value of the cosmological constant in the universe?
The current value of the cosmological constant in the universe is estimated to be around 10-29 g/cm3.
What led Einstein to hypothesize the cosmological constant?
The brief layman's answer: Einstein was troubled because his own theories of relativity did not support the idea of a constant universe, the universe that he preferred to believe existed. His equations showed that a steady state universe would eventually give in to the forces of gravity. He developed the cosmological constant, basically a 'fudge factor', so that his theories could support a steady-state universe. Shortly after, Hubble's redshift observations provided evidence that the universe is expanding, and Einstein called the cosmological constant the worst blunder of his life. Ironically, interest in the cosmological constant is returning, as a possible way of explaining the acceleratingexpansion of the universe.
What is the new discovery of the universe?
A huge structure of pulsars/quasars which defies the cosmological constant.
How was the cosmoligical constant proved wrong by Hubble?
Hubble's discovery of the expanding universe in the 1920s provided evidence against the static universe model favored at the time, which relied on a cosmological constant to maintain stability. By observing that galaxies were moving away from each other and the universe was expanding, Hubble's findings contradicted the need for a cosmological constant to explain a static cosmos.
Why did Einstein develop the cosmological constant and what was his motivation behind its creation?
Einstein developed the cosmological constant to counteract the force of gravity and maintain a static universe in his theory of general relativity. His motivation was to explain why the universe appeared to be static and not collapsing under the influence of gravity.
What is cosmological constant?
The cosmological constant, denoted by the Greek letter Lambda (Λ), is a term introduced by Albert Einstein in his equations of general relativity to account for a static universe. It represents a form of energy density that fills space homogeneously and has a repulsive effect, counteracting the gravitational pull of matter. In modern cosmology, it is associated with dark energy, which is thought to drive the accelerated expansion of the universe. The value of the cosmological constant is crucial in understanding the universe's fate and its large-scale structure.

What was named after Albert?
There are hundreds of things named after Albert Einstein. Among them are Boseâ??Einstein statistics, Einstein's constant, Einstein's radius of the universe,Einstein coefficients, and Einstein cosmological constant to get the list started.
What is Einstein worst blunder?
The "cosmological constant".
What was the greatest mistake he ever made according to albert Einstein?
Adding the cosmological constant to his Theory of General Relativity.More Information:Something keeps the universe expanding at an accelerating rate, we call this something unseen force or dark energy.After measuring and studying the effects of this energy, it appears that it has been a constant force for the entire life of our universe. This force may be something that emanates from spacetime itself. - - A constant force!? - - Maybe a cosmological constant!? - - He may not have understood it or properly quantified it, or even believed in it, but maybe Einstein got it right.
What might be the fudge factor in the Einstein equation?
The fudge factor in Albert Einstein's equation in 1917 may be due to Neutrinos which has greater speed than that of light. The difference between the speed of light and the Neutrinos may be the measure of the expansion of the universe which may ultimately cool down into ice one day.
How can Earth be located at the center of the observable universe if you accept the cosmological principle?
According to the cosmological principle, from ANY point it would seem as if we are at the center of the Universe.According to the cosmological principle, from ANY point it would seem as if we are at the center of the Universe.According to the cosmological principle, from ANY point it would seem as if we are at the center of the Universe.According to the cosmological principle, from ANY point it would seem as if we are at the center of the Universe.
